Strong Points
Function
The Socomec RF system is designed to replace Ethernet LAN network infrastructure and Modbus RS485 multi-drop wiring runs with a secure local wireless network. The RF systems has been designed to be networked from different locations throughout a facility or campus environment. The RF END-Node has an RS485 input to connect to any Modbus device that needs wireless communication, while the RF HUB-Node converts the wireless communication into an RS485 or Ethernet bus, making compatibility and integration seamless with all EMS/BMS systems.

Advantages
Easy installation
The Socomec RF system is designed to improve installation safety and reduce overall installation time:
- Wireless RS485 network saves both time and money eliminating costly wire runs.
- The RF END-Node is self-powered by the DIRIS MCM meter and can be mounted directly on top of it.
- (1) RF HUB-Node can support up to 8 Modbus devices on a network.
Easy commissioning
- Configuration with a simple and intuitive PC application (RF-View) via a direct USB connection to RF HUB-Node.
- Visual signal strength feature guarantees optimal device placement for maximum network coverage.
- (1) RF HUB-Node can support up to (8) different Modbus devices on one network.
Rugged Industrial design
- Aluminum body case.
- Extendable and multi-position antenna provides unlimited mounting options and avoids communication losses.
- Easy-access LED status lights
- RF Encryption ensures data confidentiality.
Programmable / Customizable
- Equipped with an automatic communication retry feature to ensure no data packets go missing.
- Configurable“ Prefetch” mode lets the user program the system to improve data reliability and response time to Modbus Host.
- Assign one RF END-Node to a specific Modbus address
- Using Test utility allows user to see data results while both on and off site.
